    do {
        let signInResult = Amplify.Auth.signInWithWebUI(presentationAnchor: self.view.window!)
        if signInResult.isSignedIn {
            print("Sign in succeeded")
        }
    } catch let error as AuthError {
        print("Sign in failed \(error)")
    } catch {
        print("Unexpected error: \(error)")
    }
}

Contents to be modified

func signInWithWebUI() async {
    do {
        let signInResult = try await Amplify.Auth.signInWithWebUI(presentationAnchor: self.view.window!)

            print("Sign in succeeded")
        }

and the first error says: No calls to throwing functions occur within try expression.

@dcristolovean
Since Amplify.Auth.signInWithWebUI(presentationAnchor: self.view.window!) is an async throws function, is there an error if I don't add try await?

[dcristolovean]

Other stuff happens then :).

Long story short, I'm try to investigate migration from pre-Amplify code (and some AWSMobileClient) to Amplify and the process is slow and painful.
The doc is full of inconsistencies like that, code that doesn't work and so on.
Not to mention a complete lack of how to use Amplify without the json file, creating everything in code. Very disappointing, it was the exact same thing years ago when we first implemented it and it's the exact same now with Amplify.

I'm sorry, how is this completed or fixed in any way ?

Both of these in the documentation don't even compile. Please fix this and provide a better documentation.
